ADJUSTABLE DELAY DEV ICE FOR ORDNA NGE-FUSES.

Application filed March 16,'1912. Serial NO. 684,084. I

My'invention relates to fuses for ord.

nance; and the object of myinvention is to provide means for regulating the detonation of percussion caps or primers carried by a percussion plunger and controlling the explosion of the shell.

My invention comprises an adjustable firing pin movable to a plurality of positions, usually two, wherebyeither of a pair of percussion caps or primers may be exploded; both caps or primers communicating with flame passages leading to the shell burstin'g charge. Behind one of the primers or percussion caps a' delay powder grain -is-located, by which the ignition of the shell charge can be delayed.

'lhese'and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings forming part hereof, in which:

Figure 1, is a sectional elevation of the head of an explosive projectile of the type to which my invention may be applied, showing the firing pin in one position; Fig. 2, is a similar view showing the firing pin in another position; Fig. 3, is a plan view on the line a'zz, Fig. 1; Fig. 4, is a plan view on the line bb, Fig. 2; Fig. 5, is a view illustrating a detail of the construction shown in Figs. 1 and 2; Fig. 6, is a sectional elevation similar to Figs. 1 and 2, illustrating another form of firing pin and means fol-adjusting the same; Fig. 7, is an enlarged plan view on the line (2-0, Fig. 6, and Fig. 8. is asectional elevation. on the line 1 -41, Fig. 6.

The'dclay device includes a percussion plunger 1, and an ad ustable firing pin 9...

The percussion plunger carries two primers or percussion caps, aud t; the primer or percussion cap 3 being disposed in a passage in the plunger 1, which passage also contains a delay powder gram 6, while the other primer or percussion cap is disposed in apassage 5 without a delay powder rain. Upon impact and contact of the longer with the firing pin, delay is obftaind when the primer or percussion cap 3 the firing pin being disposed toward the Patented. July 9, 1912.

left. The-firing pin 2 is slidable horizontally; a spring 8 tending, inthe position of the structure as illustrated in the drawings, to push the said pin tojthe right, but the said'pin is kept in the illustrated position by the inner wall of 'a rotary setting plate 9. \Vhen a recess 10 formed in the wall of said plate is brought to a position opposite the right end of the pin as illustrated in the drawings, the latter is moved by the spring 8 a limited distance to the right, bringing the point 7 thereof in line with the other primer or percussion cap located in the passage provided with the delay powder grain.

2,v et seq., is hollow, and an internally disposed spring is shown adapted to react upon rated at 13; the pin being inserted with the point uppermost and then turned to place such pin in the operative position. It may be held in such position by means of a lug l4 fitting the slot 13. This construction is more fully shown. in Fig. 5. It is, of course, possible to organize a structure in which the spring is disposed externally of the pin.

In the drawings a setting plate having a single recess is shown. It is of course possi ble to provide a setting plate having a plurality of recesses, or to replace one of such recesses by a projecting part 10 on the other side of a setting plate 9 (diametrically opposite), as 'shown in Figs. 6, 7 and 8. The' The form of firing pin shown in Figs. 1,

a plug 11 engaging the wall of the setting path, the walls of which are equi-distant at oints. In lieu-of this arrangement, the

all setting plate may have a cam groove as illustrated zit-15, Fig. 7, in broken lines; the firing pin, in such instance being provided with lugs for operative engagement with such groove.

in the disposal of the setting platesas I illustrated in the drawings, they must be moved a quarter turn to efi'ect changes in the position of the firing pin. The operative parts of such setting plates, however, might be set closer to the position 0;" change so as to lessen the amount of movement to effect sucl1.changed positions.

To insure movement of the percussion plunger with the primers or percussion caps always in position to be engaged by the firing pin whether the latter is in one or the other of its positions, uiding means may be provided. Theseguiding means maybe in the form of a groove 16 formed in the passage, with a corresponding lug 17 carried by such percussion plunger.

I claim:
